The most popular polyurethane (PU) in the market are PU 75 ShA and PU 90 ShA.
So PU is harder than rubber in 35-60%.
It's has lower friction coefficient and it is much more long-lasting material.
But it also has squeak in humidity and can be broken more easily.
So there is no clear answer with benefits of use just for simple driving
(while professionals use it widely in race).

Thanks for the reply! I agree that the poly FCAB will have no performance benefit for street driving. I'm mainly looking for an improvement in subjective feel. An increase in durability would be nice too.
